PowerPoint reviewing the basics of DNA, how it differs between prokaryotic and eukaryotic cells, the structure of a chromosome (unpicking the differences between chromosomes and chromatids), haploid/diploid terminology and what homologous chromosomes are. Where possible, there are links to previously taught year 1 material. This also has a video embedded which introduces the fateful encounter hypothesis, but then uses the video to ask the students to think about the structure of mitochondrial DNA. The PPT contains notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic.
